Meteor showers bring moon geysers. A lunar orbiter spotted extra water around the moon when the moon passed through streams of cosmic dust that can cause meteor showers on Earth.
The water was probably released from lunar soil by tiny meteorite impacts, planetary scientist Mehdi Benna of NASA Goddard Space Flight Center in Greenbelt, Md., and colleagues report April 15 in in Nature Geoscience.
Those random impacts suggest water is buried all over the moon, rather than isolated in freezing dark craters — and that the moon has been wet for billions of years.

NASA funding time again.
The moon has water?
“NASA funding time again.”
Indeed it is. However, robotic missions to the moon will give much more science than man missions to the moon based on costs. Perhaps in the far future when costs of payload to the moon are reasonable man may have a mission, but it is not today.
All the payload that is needed for a maned missions and return far exceeds the costs of robotic missions. If one looks at the Apollo missions to the moon the vast majority of the payload was devoted to putting a man on the moon and return to lunar orbit and return to earth. If man was not on those missions all of that payload could have been devoted to robotic missions that would have returned great science for months and perhaps years.
This is not criticism of those missions. They were an incredible feat of engineering. However, those missions were driven by politics and not science.
“A lunar orbiter spotted extra water around the moon when the moon passed through streams of cosmic dust “
Which, to anyone with common sense, would suggest that the water was in the cosmic dust. The two most abundant elements in the Universe are Hydrogen and Oxygen.
If there was extra water on the moon SURFACE after a meteor shower, then the theory stated in the title would make more sense.
The 'facts' were that they found water AROUND the moon after the moon passed through a cosmic dust storm. If their 'theory' (that microscopic dust hits the surface of the moon and splashes water miles up above the moon surface) were true, then one would think that water would be pulled by gravity back to the moon surface. That doesn't seem to be the case.
Oxygen is #3.
dust hits the surface of the moon and splashes water miles up above the moon surface...
What is the temperature of that “water”?
Between 32 and 212 F ?
” If their ‘theory’ (that microscopic dust hits the surface of the moon and splashes water miles up above the moon surface)”
RTFA!
Between 32 and 212 F ?

LOL — Valid point. You’d need to adjust your temperature range for liquid water from what you have (which is the range at the atmosphere pressure existing at sea level on Earth) to the range it would be in the atmospheric vacuum at the moon.
Thanks.
The moon.
So close in terms of the universe that it’s ridiculous.
What the hell is out there that we don’t know about.
Did it civilizations come and go already?
Can we Really be the only intelligent life forms out of 10^21 planets in the universe?
And scientists are studying water in a cosmic dust storm. I guess you work with what you have.
God I feel tiny.
At my weight, that’s a good thing :)
Mercury, Venus, Earth, Mars and all their moons are IN the ATMOSPHERE of the Sun. Recently scientists 'figured out' that the Moon is IN the ATMOSPHERE of the Earth. It's a small solar system.
What the hell is out there that we don’t know about.
Much more than we think we 'know'.
Yeah, but who cares about Helium ?
David Bowie did when he sang, “Fame,” on stage.
Heh!
Based on their theory then it would probably have been vaporized by the heat from a meteorite striking the surface hard enough to penetrate to an extreme depth. So it would be very hot. Then, according to their theory, that vapor would have risen through the atmosphere (sic) and float around the Moon. I'd guess it would get very cold. Depends on which side of the Moon the water was floating around on. In the Sun, hot, out of the Sun, cold.
SO... to answer your question, I don't have a clue.
I don’t have a clue....
Me either.
My point, it is not liquid water, it is either vapor or ice.
Maybe jumping back and forth depending on location.
There are some subjects some folks don’t want you to be logical about. But don’t you change.
talking molecules, what if the ejection force/escape velocity is stronger than the minimal gravity?
I’ve long wondered why we haven’t put up two upgraded (Moon mission specific) versions of the Mars rovers to drive around taking surface samples, drilling, etc.
All off the shelf tech just need to get them up there. Drive around a bit with easy communications of huge amounts of data back to JPL/Nasa. Here’s hoping ... ;-)
